CINCINNATI, Nov. 6, 2012 /PRNewswire/ -- Omya Inc. is voluntarily recalling certain lots offood grade ground limestone products processed at its Superior, Arizona plant because of the possible presence of Salmonella. There have been no reports of any illnesses or adverse health effects associated with any of Omya's food grade ground limestone products. Although an investigation is still ongoing, Omya is recalling specific lots of Omya-Cal FG-4 AZ, Omya-Cal FG-10 AZ and Omya-Cal FG-15 AZ in the U.S. as a precaution. Omya's voluntary recall is being conducted in consultation with the U.S. Food and Drug Administration (FDA).

The most common symptoms of Salmonella infection are diarrhea, abdominal cramps and fever, which develop within eight to 72 hours of eating contaminated food. The illness usually lasts for four to seven days and most people recover without treatment. However, salmonellosis can be severe or even life threatening for infants, older people, pregnant women and those with weakened immune systems. Individuals experiencing these symptoms should seek medical attention.
